[Sn0rt]

the current version

1. the current version of gofish is not support set header with If-Match.

PATCH /redfish/v1/Systems/1/Bios/Settings HTTP/1.1
Host: 192.168.142.53
User-Agent: gofish/1.0
Connection: close
Content-Length: 41
Accept: application/json
Content-Type: application/json
Cookie: sessionKey=xxx
X-Auth-Token: xxxx
Accept-Encoding: gzip

{"Attributes":{"PXE3Setting":"Disabled"}}

the server will give a response and the status code is 429 .

how to solve this problem : firstly get the setting target, and reuse the header of the response of the query.

for example

curl -k -v -u 'username:password' -XGET https://192.168.142.53/redfish/v1/Systems/1/Bios/Settings -H 'Content-Type: application/json'

then reuse the ETag from the response , the etag value is W/"93227b24"

curl -u 'Administrator:Admin@9000' -XPATCH https://192.168.142.53/redfish/v1/Systems/1/Bios/Settings -d '{"Attributes": {"PXE3Setting": "Disabled"}}' -k -v -H 'Content-Type: application/json' -H 'If-Match: W/"93227b24"' -s | jq
